Oooh ... that's not possible and I'll explain why.
Genius is the ultimate expression of happiness. Geniuses are the happiest personalities in history, to some extent it is by them that we count happiness, perhaps this is the only reason why they remained in our memory and all their activities are a manifesto of the fullness of their happiness, which remained to us in their documents.
Therefore, if you have doubts, if you regret, if you cannot show the world how happy you are, you are not a genius and you will never become one.
Intellect has nothing to do with it.
(If you say that there was once at least one inferior, sick, decadent, unhappy, insane genius (Baudelaire, Nietzsche, Pascal, etc. .) - I will object to you: Lautremont is the author of also and "Poems")
well, we need to define what a genius is in general. this is something like a creator, a "craftsman" to see something new in the familiar, an innovator. It seems to me that the connection with the intellect here is the opposite - it is not worth "gaining aikyu to become a genius", but "becoming a genius in order to gain intelligence") Try to create. At least to compose jokes yourself is already "strained for the brain" in our easy time. What can we say about what engineering and technical creations. You must also understand that no one can be brilliant "in everything", but almost everyone is brilliant in something) The main thing is to find. And for this you need to "try everything in life")
